Abstract(s)

Parasitic diseases caused by gastrointestinal nematodes (GIN) are considered important limiting factors for livestock production worldwide, as they significantly compromise animal welfare and increase production costs. For years, parasite control has relied exclusively on the use of synthetic drugs. Resistance of GIN to commercial anthelmintics has been increasingly reported throughout the world. Therefore, alternative approaches have emerged for controlling GIN in farm animals, including the exploration of plants with bioactive potential. Tithonia diversifolia can be harvested year-round, and all parts of the plant have been used in folk medicine for a wide range of diseases. This study evaluated the in vitro antioxidant properties of water and 70% aqueous acetone extracts of T. diversifolia aerial parts, including leaves, branches, and flowers, using radical-based methods, and assessed its anthelmintic potential through a parasite model, employing the egg hatching assay (EHA) with water extracts. Additionally, the total polyphenolic content of the extracts was determined. These findings highlight T. diversifolia as a promising natural source of antioxidant and anthelmintic compounds.
